I'm brand new to Ardruino so I have a question that has probably been answered many many times... I couldn't find it in the search however.
We are making an automated demolition derby car for my Intro to mechanical engineering class using the ardruino duemilanove microcontroller and I had a question.
I want to wire the motors directly the microcontroller, but I'm not sure how I would control the motors. By that I mean, how do I tell the microcontroller to move forward AND backward. and how do I tell it to move left AND right. I know how to set pins high, but that only works for one direction as far as I understand. Any help would be greatly appreciated.
